Irwin Strait-Line 5 lb Fluorescent Orange Powder Chalk is the professional's choice for exterior use. This micro-fine chalk provides more marking power and comes in a plastic squeeze bottle for easy application. The newly engineered flip-top cap keeps the chalk in the bottle and prevents it from spilling. This chalk lasts longer and is ideal for low-light applications such as laying sub-floors in basements. It may also be used to show layout changes and is great for roofing, masonry, tiling, plumbing, and electrical work.
